US teen admits video livestreaming crash and death of sister makes her look like 'a monster'

The US teen who livestreamed the horrific crash that killed her younger sister has said she often filmed herself whilst driving, and admitted the video makes her look like "a monster".

Obdulia Sanchez, 18, recorded live footage on Instagram of herself singing along to music as she drove a car in Central California, with 14-year-old sister Jacqueline and another teen as passengers, at the end of last month.

Speaking to NBC Fresno affiliate KSEE from jail where she is currently being held on $300,000 bail, Sanchez said she drove while filming herself on social media often but had never crashed.

"I didn't even know I looked like a monster — like, I look like a freaking horrible monster,” Sanchez told KSEE of the video she took following the accident as her sister died.

"That was not my intention at all."

Police say Sanchez overcorrected a turn, causing the white sedan to swerve across lanes, crash through a wire fence and overturn into a field.

Jacqueline was pronounced dead at the scene while the other teen, Manuela Seja, is recovering from major injuries. Sanchez walked away with minor injuries.

Commenting on the crash, Sanchez said she started to freak out when she realised her sister and friend were no longer in the backseat as they had been ejected from the vehicle at some point during the accident.

While Sanchez did initially turn off the live stream as she exited her vehicle, she turned it back on allowing viewers to watch as she discovered her sister's body, with the video also recording her 911 call.

"I knew she was dead because I took her pulse and she had no pulse," she told KSEE.

Sanchez has said livestreaming while driving is common amongst people her age.

“We do it all the time — all the time. Trust me, it's like a reflex. Like I haven't crashed, you know?" she said.

“Everybody does it. Everybody does. They take Snapchats. Everybody does it. Why not? People take video of them in cars like all the time. And I'm only 18 — we're still young.”

But if she had known her sister would die that day, Sanchez said she "would've never left the house – ever".
